inVATic checks both sides of the return, your input VAT and your output VAT, against your own tax code mapping. Every exception is then re-read against HMRC guidance, so your team gets one workbook with the reason, the treatment and the source for every flag.

How we handle your data
The AI only sees the information needed to review an exception.
- Only the ledger export.You send the export. We never need a login to your ERP or access to your invoices.
- Names stay out of the AI review.Supplier names and invoice numbers are replaced with labels before an exception is sent, and mapped back afterwards.
- Every request is logged.Each AI review request and response is recorded, so any suggestion can be traced.
- The final say stays with you.inVATic flags exceptions and suggests treatments. Your team reviews each one and records Accept, Reject or Query. It doesn't file returns or provide tax advice.
